Question

b. 3x - 2y = 18 for y

Explanation:

Step1: Isolate the y-term

Subtract $3x$ from both sides:
$3x - 2y - 3x = 18 - 3x$
$-2y = 18 - 3x$

Step2: Solve for y

Divide both sides by $-2$:
$\frac{-2y}{-2} = \frac{18 - 3x}{-2}$
$y = \frac{3x - 18}{2}$

Answer:

$y = \frac{3x}{2} - 9$ or $y = \frac{3x - 18}{2}$
